GLUE IN "PEARL" FORM
Discussing Scientific Processes, British Expert
Tells of the Obvious Advantages of New
Glue Making Methods.
The manufacture of glue, perhaps one of the oldest
industries extant, has only recently passed beyond
the state of "glue-boiling," says A. V. Underwood,
M. S., writing in the London Music Trades Review.
Modern firms engaged in the production of glue
have now succeeded in so perfecting the boiling proc-
ess, which constitutes the first stage of manufacture,
that the human element is practically excluded, and
the glue, prior to drying, may be considered quite
reliable and pure for all practical purposes at this
stage On the other hand, the drying process is still
essentially carried out in the old-fashioned, primitive
way.
The pouring out and slow drying of the glue slabs
not only calls for a large amount of manual labor,
but also involves a good deal of uncertainty with re-
gard to the finished article. In addition to the risk
of decomposition of the glue by bacteria or moulds,
there is the difficulty of regulating the lengthy dry-
ing process so as to ensure the production of a uni-
form quality. This uncertainty affects the user of
glue quite as much as the producer, and it is to the
interests of both that the product should be stand-
ardized as much as possible.
The obvious way of eliminating the disadvantages
referred to is to accelerate the drying process as much
as possible and to exclude manual labor from it.
Only in this way can the deterioration of the prod-
uct, while semi-liquid or moist, be prevented. Need-
less to say, numerous experiments have been made in
this direction, but generally without success. Theor-
etically a product in powder form would be most de-
sirable, but actually it involves many practical diffi-
culties.
Through the prolonged researches of Continental
chemists saccess has at last been attained in acceler-
ating the drying process, and at the same time pro-
ducing an article that can immediately be recognized
?.s glue. In this process the liquid is not allowed to
dry as powder, but in the shape of small droplets or
so-called "pearls." These are obtained by spraying
the concentrated glue solution through an inert heated
medium. The beads thus formed arc hardened imme-
diately and the drying is quickly completed without
their losing shape. The whole process takes above
eight hours for completion instead of the three weeks
which arc required for drying the glue in the form of
slabs.
There are also additional important advantages in-
herent in the new form of glue. When glue in slab
form is required for use it has to be soaked for a
period of 12 to 24 hours to enable it to absorb the
necessary quantity of water before it can be heated.
In the case of these "glue-pearls" the period of soak-
ing is reduced to 30 minutes.
Quite apart from these advantages it will easily be
seen that there is a definite saving in the actual quan-
tity of glue used. It is no longer necessary to make
up glue in advance of immediate requirements and
run the risk of deterioration through frequent reheat-
ing, as the ease with which the pearls are made up
enables the glue to be prepared in small quantities as
required. All waste due to the decomposition of glue
through standing in heated workrooms and through
throwing away of water in which glue has been
soaked is entirely avoided. Practical experience has
shown that there is actually a saving in material
through these causes of 10 per cent to 15 per cent
compared with the use of the old-fashioned slabs.
A further benefit results from the fact that it is so
very easy to make up glue of the proper strength.
It is only necessary to measure out equal volumes of
the "pearls" and water to ensure the correct result.
In using slabs there is always an uncertainty as to
the exact quantities actually used unless the quite
impracticable method of weighing out the quan-
tities were adopted, and consequently the resulting
glue may be stronger or weaker than desired.
MUSIC GOODS IN HAWAII
Island, Now Attractive to American Manufacturers,
May Be Part of Domestic Market.
Hawaii is becoming attractive as a market for
American manufacturers of musical instruments, rolls,
records and sheet music and quite a few companies
are taking steps to establish branch houses and
agencies there. Even the ukulele business is now
shared by American manufacturers.
Ordinarily Hawaii should be regarded as a part
of our domestic market. Goods may be shipped to
Hawaii as easily as from one state to another. No
customs regulations have to be complied with and,
for that reason, the details of the transaction differ
little from those of ordinary domestic business. Com-
panies which do not export to foreign countries may
very well ship to Hawaii, using the same force of
employees that handles shipments to their continental
customers.
An American business owned by an individual or
a partnership may establish a branch in Hawaii
without legal restriction under the protection of the
United States constitutional provisions.
In establishing an agency two things might be
done; first, the sending of a representative from the
mainland as a selling agent, who would come under
the ordinary interstate commerce law and not be
required to take out a merchandise license. In the
event of his selling goods through a local agency,
he would then be required to take out a peddler's
or merchandise license; second, if a local representa-
tive were appointed as agent for a mainland house,
